A predetermined portion of the energy available in a flowing fluid within a pipe is converted to torque in a rotating system outside the pipe. The rotational energy thus obtained is available to other uses at the end-user's discretion. A preferred embodiment comprises a magnetic turbine with blades ( 705 ), and includes an external rotating ring ( 720 ) with attached pole pieces ( 710-715 ) comprising either permanent magnets, or electromagnets with coils ( 745-750 ) which are connected through slip rings (not shown) to an external power source (not shown) and thereby energized. Attraction between the pole pieces and the rotating turbine causes the external ring to rotate. A mechanical coupling ( 730 ) couples the ring to a generator ( 732 ) or other load such as a grinding wheel (not shown) through a shaft ( 725 ).
